Intel ARC A750 & Spectacle Issues


I have an A750 that is running great on KDE Plasma in a fully updated Tumbleweed. Hardware encoding, OpenCL/GL and everything appears to be working properly. The motherboard is a ASUS Prime X570-Pro with a Ryzen 7 5700X, so there is no integrated graphics to interfere with anything. Re-sizable Bar is enabled. The monitor is a Samsung UR55 4K using the display port.

When selecting Rectangular Region to take a screenshot with Spectacle, I get a bright white fog over light colored windows to the point it’s hardly usable (it makes black text on a white background lighter). Changing “Use light background” in Spectacle Configure menu doesn’t appear to make any difference either way.

Using “Window Under Cursor” doesn’t capture the desired window but just a section of the screen with part of the window. Using Active Window works. Full Screen with a 1 second delay works. I cloned my Tumbleweed NVMe SSD to a USB enclosure and plugged it into my wife’s computer and Spectacle worked great. She has the exact same hardware except she has a RX580.

Also, using ALT+Shift+F12 to turn off the compositor fixes Spectacle with the A750. I’ve studied this pretty good and haven’t found anyone with the same problem. I also installed Spectacle from Mageia 9 and it has the same issues.

I didn’t not try HDMI yet, I forgot. I have not noticed any problems with Blender, Darktable, GIMP, VLC or the desktop etc. I did find wherhe the Spectacle developers made changes to how it displays the selection area but that’s been a couple of months ago.

I’m open to ideas from anyone who may have a clue what the problem is.

Thank you.

I found a workaround here.

I just noticed that if Spectacle is set to use last-used capture mode when opened
(Rectangular Region for me), the screen is not bleached.

I’m experiencing this same issue. Oddly though, on TW it works as it should, but with openSuse MicroOS Kalpa, that’s where I see the “bleached” issue. I’ll compare the settings of both - thanks!
